SPECIFICATION forming part of Letters Patent No. 635,671 dated October 24, 1899.

Application filed July 18,1899. Serial No. 724,255. (No model.)

To aZZ whom it may concern.-

Be it known that I, FRANKLIN I-IoWLAND DAWEs, of El Reno, in the county of Canadian and Territory of Oklahoma, have invented a new and Improved Plow, of which the following is a full, clear, and exact description.

The object of my invention is to construct a plow particularly adapted to localities where the rainfall is limited and which will loosen and level the soil without turning under the crust of dry soil on the surface, as is done with the'moldboard of the plow, so that when the grain is sown it will be placed directly in moist soil.

Another object of the invention is to provide a scaling or surface share and a vertical cutter at the landside of the share so shaped that it will turn the soil away from the beam and to provide adjustable teeth at the rear of the share adapted to loosen the soil as it passes over the share and back into the furrow.

Another object of the invention is to provide the plow with a combined leveling and pulverizing device and means for raising and lowering the device, regulating the ends of the rake-head of the device to the furrow, and for setting the rake at an angle or straight and even with the furrow.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth,

and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar charactersof reference indicate corresponding parts in all the figures.

Figure l is a perspective view of the improved plow and its attachments. Fig. 2 is a detail perspective view of the share and cutter used in connection therewith together with a portion of the landside. Fig. 3 is a plan view of the landside end of the share and a plan view of the cutter. Fig. 4 is a detail view of the cutter that is attached to the share and landside. Fig. 5 is a vertical section through the rake-head of the leveling and pulverizing device; and Fig. 6 is a transverse section through the bar carrying the teeth located immediately at the rear of the share, showing one of the said teeth in side elevation.

The beam A and landside B may be of any desired length, and the forward end of the landside B is provided with an inclined upper edge 10, the inclination being downward and forward, as shown in Figs. 1 and 2. A plate 11 is firmly secured at one of its ends on the beveled surface 10 of the landside following the inclination of said surface, as

shown in Fig. 2, and this plate 11 is adapted to carry a share 0, which follows the inclination of the plate 11 and the surface 10 of the landside. This share is attached to the plate by rivets or equivalent means, and at the lower portion of its landside end a point 12 is formed, while the upper edge at the landside end is cut away, as indicated at 13 in Fig. 2. This is done in order that the landside end of the share 0 may be free from its supporting-plate 11 and have more or less of an upward inclination.

A cutter D is located at the landside end of the share. This cutter is provided with a notch 14 in one of its edges, as shown in Fig. 4, so that the lower edge of the upper portion (1 of said cutter may be carried over upon the plate 11, supporting the share, to a point below the cut-away portion of the share, as is particularly shown in Fig. 2, while the lower end of the opposing portion 61 of the said cutter may be carried downward to an engagement with the left-hand side of the landside B. Suitable bolts are used for securing the two portions of the cutter to their respective supports, and the upper rear portion of the cutter under this construction is provided with a decidedly-curved inner surface 01 as shown in Figs. 1 and 3, which surface tends to direct the soil away from the beam A to the rear edge of the share 0. The forward or cutting edge of the cutter D inclines downwardly in direction of the point of the share.

'Abar 15 is pivoted at the rear of the share 0, the ends of the bar being mounted to turn in brackets 16 and 17, the bracket 16 being secured to or projected from the heel of the plate 11, while the bracket 17 is secured to the inner or right-hand surface of the landside, as shown in Fig. 1. The bar after it has been adjusted on its trunnions may be held in its adjusted position by placing suitable nuts on the outer ends of the t-runnions, which portions are threaded.

A series of teeth 18 is secured to the bar 15. These teeth are at an opposite angle to the share 0, extending downwardly and rearwardly, but the teeth may be given any desired inclination by the adjustment of the bar 15, referred to. These teeth 18 are preferably provided with flat or horizontal shanks that are secured to the bar and with bodysurfaces at an angle to the shanks. The bottom or under edges of the body of the teeth are convexed at their lower ends to a greater or less extent, and the upper edges at the same ends of the teeth are concaved, as shown best in Fig. 6; but the entire upper edge of the body of each tooth 18 is a cutting edge. These teeth serve to loosen the soil as it passes over the back of the share into the f urrow. Suitable handles 19 are secured to the landside B, and these handles are usually connected also with the standard or beam A by means of suitable braces 20.

In connection with the share O, cutter D, and the loosening devices-namely, the teeth lS-a leveling and pulverizing device E is employed. This leveling and pulverizin g de vice is usually connected with the plow bya clip or clamp 21, attached to the standard or beam A or other convenient place on the plow that will enable the leveling and pulverizing device to work in the furrow. \Vhen the clamp or clip 21 is secured to the beam A, said clamp is provided with an extension 22, that projects slightly downwardly and rearwardly and inwardly and rearwardly and in direction of the right-hand side of the plow, as illustrated in Fig. 1. A bar 23 is used in connection with the clamp 21 and its extension, and this bar consists of a horizontal head-section a and a body-section a, whose side faces are vertical. The head-section a of the bar is provided with a pivot 24, that passes through the extension of the clamp 21, and said head-section a of the bar 23 is further provided with a segmental slot 25, that receives a tightening-bolt 26, the bolt passing into the extension of the clamp, as is also shown in Fig. 1. This adjustment of the bar 23 with reference to the clamp 21 enables the leveling and pulverizing device to be carried to the right or to the left, as desired.

The shank 27 of the leveling and pulverizing device is made in two sections e and e, having a swivel connection 2S and a suitable tightening-bolt at said connection, and the shank 27 of the leveling and pulverizing device is pivoted at its forward end by a pin 29 to the forward portion of the body-section a of the supporting-bar 23. This swivel con nection provided in the shank of the leveling and pulverizing device enables the ends of the rake-head of the leveling and pulverizing device to be adjusted properly with relation to the furrow, while a vertical adjustment of the entire leveler and pulverizer is accomplished through the medium of a lever 30, pivoted to the body-section a of the supporting-bar 23 and connected bya link 31 with the forward section of the shank of the leveler and pulverizer. The lever 30 is provided with a suitable thumb-latch adapted to engage with a rack 33, secured to the supporting-bar 23, as illustrated in Fig. 1.

The rear end 34 of the shank 27 of the leveling and pulverizing device is flattened horizontally, and the flattened portion is provided with a segmental slot 35. A carrying-plate 36 is located upon the flattened portion 34 of the said shank, as shown in Fig. 1, and the rear end of this plate is bifurcated. The ends of the members thus provided are formed with eyes 37, in which a rake-head 38 is mounted to turn. The body portion of the carrying-plate 36 is ad justalol y attached to the shank by passing a tightening-bolt 39 through the said body and through the segmental slot 35. This adjustment of the rake-heads enables the rake-teeth to beset at any desired angle to the furrow or straight and even with the furrow. The teeth 39 of the rake-head are curved at their-lower ends, and their forward edges are cutting edges.

The teeth 39* may be placed at any desired angle vertically to the ground by turning the rake-head 38. This is accomplished through the medium of a handle 1O, secured, preferably, to the central portion of the head 38, and

this handle is moved along the surface of a' rearwardly-curved guide-bar4l,which guidebar is provided with a series of apertures, any one of which is adapted to receive a pin 42, and this pin is likewise intended to be passed through the handle 10 after the adjustment of the handle.
